What is the landing stall speed (Vso) for many light aircraft?

The landing stall speed, often referred to as Vso, is the airspeed at which a specific aircraft will stall in a landing configuration, typically with full flaps and landing gear extended. For many light aircraft, this speed generally falls within a range around 40 knots, making option A a valid and representative choice for a number of popular models.

It's essential for pilots to understand Vso because knowing this speed helps in managing performance during approach and landing phases. If the aircraft descends below this speed, it risks entering a stall, which can lead to loss of control, especially close to the ground.

Other speeds listed, like 42 knots, 45 knots, and 38 knots, may apply to specific aircraft but do not represent the general estimate for many light aircraft. Because various aircraft have different designs and configurations, Vso can vary, but around 40 knots is a common benchmark across a wide array of light aircraft models. Always consult the specific aircraft’s Pilot Operating Handbook (POH) for the accurate Vso.
